“…However, studies on manikins always have to be interpreted with great caution when considering the clinical implications of airway management in anaesthesiology . The anatomical correlation between the level of the teeth and the hypopharynx often varies from manikins to patients and could enable easier application in manikins . Furthermore, the tissue conditions are less realistic due to the absence of mucus and other fluids like blood that could impede the view.…”

“…The adult high-fidelity simulator SimMan (Laerdal medical AS, Stavanger, Norway) offers sufficient conditions concerning the airway anatomy 14. The airway of the simulator was modified by the producer’s default settings, as follows: pharyngeal obstruction, tongue swelling, reduced range of head reclining and jaw trismus.…”

Impact of cardiopulmonary resuscitation on a cannot intubate, cannot oxygenate condition: a randomised crossover simulation research study of the interaction between two algorithms

ObjectivesDuring a ‘cannot intubate, cannot oxygenate’ situation, asphyxia can lead to cardiac arrest. In this stressful situation, two complex algorithms facilitate decision-making to save a patient’s life: difficult airway management and cardiopulmonary resuscitation. However, the extent to which competition between the two algorithms causes conflicts in the execution of pivotal treatment remains unknown. Due to the rare incidence of this situation and the very low feasibility of such an evaluation in clinical reality, we decided to perform a randomised crossover simulation research study. We propose that even experienced healthcare providers delay cricothyrotomy, a lifesaving approach, due to concurrent cardiopulmonary resuscitation in a ‘cannot intubate, cannot oxygenate’ situation.DesignDue to the rare incidence and dynamics of such a situation, we conducted a randomised crossover simulation research study.SettingWe collected data in our institutional simulation centre between November 2016 and November 2017.ParticipantsWe included 40 experienced staff anaesthesiologists at our tertiary university hospital centre.InterventionThe participants treated two simulated patients, both requiring cricothyrotomy: one patient required cardiopulmonary resuscitation due to asphyxia, and one patient did not require cardiopulmonary resuscitation. Cardiopulmonary resuscitation was the intervention. Participants were evaluated by video records.Primary outcome measuresThe difference in ‘time to ventilation through cricothyrotomy’ between the two situations was the primary outcome measure.ResultsThe results of 40 participants were analysed. No carry-over effects were detected in the crossover design. During cardiopulmonary resuscitation, the median time to ventilation was 22 s (IQR 3–40.5) longer than that without cardiopulmonary resuscitation (p=0.028), including the decision-making time.ConclusionCricothyrotomy, which is the most crucial treatment for cardiac arrest in a ‘cannot intubate, cannot oxygenate’ situation, was delayed by concurrent cardiopulmonary resuscitation. If cardiopulmonary resuscitation delays cricothyrotomy, it should be interrupted to first focus on cricothyrotomy.

Ein wesentliches Problem aller Phantome ist die unzureichende Nachbildung der Speiseröhre.…”

ZusammenfassungMit der zunehmenden Anwendung von Larynxtuben in der prähospitalen Notfallmedizin, sowohl durch Notärzte als auch durch nicht ärztliches Rettungsdienstpersonal, werden zunehmend Komplikationen, auch schwerwiegender Art, beobachtet. Anhand eines Fallbeispiels von einem Patienten, bei dem es durch einen unbemerkt fehlplatzierten Larynxtubus zunächst zu einer Cannot intubate, cannot ventilate-Situation mit der Notwendigkeit für einen chirurgischen Atemweg, in der Folge zu einem abdominellen Kompartment-Syndrom aufgrund gastraler Luftinsufflation durch den Larynxtubus kam, werden die typischen Anwenderfehler und Komplikationen aufgezeigt. Den aktuellen Leitlinien der Fachgesellschaften folgend sollen in der Notfallmedizin ausschließlich Larynxtuben der 2. Generation zum Einsatz kommen, welche die Möglichkeit der gastrischen Drainage bieten. Damit diese effizient erfolgen kann, muss eine Magensonde unmittelbar nach Platzierung eingelegt werden. Kann diese nicht eingebracht werden, ist dies quasi beweisend für eine unmittelbar korrekturbedürftige Fehllage. Die Cuffdruckmessung soll zu einem frühestmöglichen Zeitpunkt vorgenommen und der Cuffdruck auf in der Regel maximal 60 cmH2O adjustiert werden, um druckbedingte Zirkulationsstörungen der Zunge mit entsprechender Schwellung zu vermeiden. Schlussendlich sollte ein strukturiertes Ausbildungscurriculum angewendet werden, dass den zukünftigen Anwender für diese Komplikationen sensibilisiert.
